How to Convert Miles per Hour to Meters per Second
To convert miles per hour to meters per second, multiply the speed by the following conversion ratio: 0.44704 meters per second/miles per hour.
Since one miles per hour is equal to 0.44704 meters per second, you can use this simple formula to convert:
The speed in meters per second is equal to the speed in miles per hour multiplied by 0.44704.
For example, here's how to convert 60 miles per hour to meters per second using the formula above.

What Is a Miles per Hour?
A miles per hour is a unit of speed equal to 0.44704 meters per second (m/s), the base unit for speed. Imperial & US road speed unit (1 mph = 1.609344 km/h). [1]
The miles per hour is classified as a US customary and imperial unit of speed. Miles per Hour can be abbreviated as mph; for example, 1 miles per hour can be written as 1 mph.
When working with miles per hour (mph) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, miles per hour (mph) are widely used across standard speed applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Meters per Second?
Coherent SI unit of velocity. It serves as a primary reference unit for measuring speed across scientific and practical applications. [2]
The meters per second is classified as an International System of Units (SI) unit of speed. Meters per Second can be abbreviated as m/s; for example, 1 meters per second can be written as 1 m/s.
As the primary coherent reference unit for speed in this category, all other speed units are mathematically anchored to the meters per second (m/s).
In practice, meters per second (m/s) are widely used across standard speed applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting speed between miles per hour (mph) and meters per second (m/s), keep full floating-point precision (1 mph = 0.44704 m/s; 1 m/s = 2.2369363 mph) during intermediate calculations and round only the final meters per second figure to match your instrument tolerance.
